Spatial inequalities in breastfeeding initiation in the United States: A multiscale analysis of county-level determinants.
Article in PLOS global public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Deepening our understanding of geographic variations in breastfeeding initiation (BFI) remains an important element in developing a comprehensive snapshot of maternal and infant health. Identifying spatial variations in socioeconomic, demographic, cultural, and environmental barriers to breastfeeding can advance intervention efforts to educate and encourage breastfeeding within a community. The purpose of this paper is to provide a comprehensive snapshot of county-level trends in BFI in the United States. Using a suite of exploratory spatial data analysis (ESDA) techniques and multiscale geographically weighted regression (MGWR), we highlight several important regional determinants of BFI and improve model performance, increasing the adjusted R2 from 0.641 in a traditional OLS model, to 0.852 in the MGWR model. We concluded the paper by identifying potential locations for public health interventions, especially in Appalachia and the Gulf Coast regions of the United States, and provide three relatively cost-effective strategies to improve BFI that focus on community support, healthcare infrastructure, and education.
